Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 19, 2024The c.66T>A (p.D22E) alteration is located in exon 2 (coding exon 1) of the AFTPH gene. This alteration results from a T to A substitution at nucleotide position 66, causing the aspartic acid (D) at amino acid position 22 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
